Update, March 21st: AMD have release a new set of Catalyst™ drivers, version 15.3 beta, which include a potential fix for the rigged mesh issues, negating the need for this workaround – see my notes here.

Update, Sunday, December 14th: user DMC Jurassic reports that the process outlined below can also be used with the OpenGL .DLL files from the AMD Catalyst 14.4 drivers. However, no ZIP file of the extracted DLLs are currently available, so Yoho’s notes at the end of the article will need to be followed to obtain them.

Also note that Singularity have issued a supplemental update to address mesh rendering issues.

On Tuesday, December 9th, I blogged about the continuing issues impacting those with AMD GPUs using the latest Catalyst and Omega drivers.

Yoho Waco offers an AMD Catalyst driver workaround for Windows users

Second Life resident, and contributor to this blog, Yoho Waco offered a workaround to the problem for Windows users who would prefer to use the latest Catalyst drivers, rather than rolling back to an earlier version.

The workaround should fix the mesh rendering issue, and while Yoho uses Windows 7 64-bit, the basic approach should work with all flavours of support windows, 64-bit and 32-bit.

I can’t actually test it myself, as I use Nvidia, but feedback indicates it works well, and so with Yoho’s permission, I’m reprinting his instructions here so that it might get broader visibility.

As many have pointed out, the issue lies in the fact that the more recent Catalyst drivers use a late version of OpenGL that is supported by SL. This being the case, Yoho provides instruction on using an earlier version of OpenGL with the more recent drivers:

It seems that the problem is in the OpenGL version has the new driver 14.12.

I tried a small solution is to take the DLL’s from version 14.9 and place them inside the folder .\SecondLifeViewer

Above left: the .DLL files from Yoho’s dropbox copied into the SL viewer’s installation folder; and above right, how they are reported by the viewer

Note that if you’re using a viewer other than the official SL viewer, you’ll need to drop the files into the relevant installation folder, rather than .\SecondLifeViewer (e.g. in the case of Windows 64-bit, instead of dropping the files into C:\Program Files\SecondLifeViewer, you would place them in C:\Program Files\[name of your viewer]).

Commenting to me about the fix, Yoho said:

I had to install version 14.9 on my computer and search for the files inside C:\Windows\System & C:\Windows\System32. Once copied, I completely uninstalled the version of the Catalyst 14.9 drivers and reinstalled the new version 14.12 Omega drivers. I used and application called DDU, as it is best to fully uninstall a driver to avoid conflicts. However, this is all very complicated, so I published my DLLs [in the dropbox link above] so users can access them and copy them to their viewer.

Do note that this workaround won’t solve the shadows issues which occur with the Catalyst 14.9.x drivers (see BUG-7947 and BUG-7627), however, Yoho informs me that when he has the time, he may try to see if he can use the OpenGL DLLs from the 14.4 drivers to see if they can be used in this approach to resolve issues, both with mesh rendering and with shadows.

In the meantime, those who would prefer to use the latest drivers and have tried this approach state it works, but as always, your mileage may vary, and the workaround is offered without liability or responsibility on either Yoho’s or my part.

My thanks to Yoho for his work in this and notifying me.

On December 4th, Oculus VR released the latest software version for the Oculus Rift, version 0.4.4. A beta release, it includes an number of bug fixes and improvements, while retaining experimental support for Linux.

As a result of this update, Strachan Ofarrel (aka Dave Rowe in the physical world) released an updated version of the Alpha version of his CtrlAltStudio viewer on Friday, December 12th. Version 1.2.2.41224 Alpha 5 brings with it not only support for the SDK update but also, courtesy of Mac viewer developer Cinder Roxley, a Mac build as well.

As usual with the Alpha version of the viewer, this release is installed into its own directory / folder, and so can be installed alongside the current release version of the CtrlAltStudio Viewer. A clean install is not required if you have been running previous alpha versions.

Core updates in this release comprise:

Updated to Rift SDK 0.4.4. This fixes the overdone vignette (fading to black) around the Rift barrel image’ edges edges.

Updated position of notification messages and script dialogue boxes so that they’re visible and usable in Riftlook.

Modified Start+Back key behaviour on Xbox controller if Rift display is configured: if you’re not in Riftlook then you enter Riftlook the same as before; however if you’re already in Riftlook then it zeros sensors the same as Ctrl+Spacebar (instead of exiting Riftlook). To exit Riftlook with the Xbox controller, press the yellow ‘Y’ button.

Updates for Mac OSX build.

Hints and Tips

Also, don’t forget that each set of release notes for the Alpha version of the viewer includes a set of hints and tips for getting the best results when using the viewer with the Rift. These include tips from Strachan and also discoveries made by other users, and are being added to over time. They include, but are not limited to:

If you have good frame rates, including while turning, set your Rift display to 75Hz: Control Panel > Display > Screen Resolution > Advanced Settings > Monitor

If you have a stereoscopic 3D system, you may need to disable stereoscopic 3D display in order to stop the Rift’s display rate being reduced from 75Hz to 60Hz. [Estelle Pienaar]

If you have an Nvidia graphics card, adding an entry for the viewer in the Nvidia Control Panel 3D Settings and setting the preferred refresh rate to unlimited may let your Rift run at 75Hz without needing to make it your primary monitor [Phoenix]

Those of us involved with and immersed in virtual worlds are very familiar with the power and opportunities they offer for educational purposes.

In January and February 2015, this will again be demonstrated in a unique way as literature, live theatre and a virtual world combine to present theatre goers and school children with the opportunity to not only witness the unfolding of one of the great stories from American literature – F. Scott Fitzgerald’s The Great Gatsby – but to actually immerse themselves in the story itself due to a new an unique collaborative partnership between the Tacoma Little Theatre (TLT), in Tacoma, Washington state, and the folk at Seanchai Library.

From on January 23rd, 2015 through until February 8th, TLT will be presenting Simon Levy’s stage adaptation of The Great Gatsby, directed by Dale Westgaard, to adult audiences and daytime audiences from local schools.

Coinciding with the play, through their extensive facilities on Kitely, the Seanchai Library will be offering audiences and schools attending performances with the opportunity to explore the world presented by the novel from the comfort of their own home or from within the classroom.

Explore Gatsby will run alongside TLT’s production of Simon Levy’s stage adaptation of the novel, giving TLT patrons and schools with the opportunity to explore F. Scott Fitzgerald’s world in greater detail

Explore the Great Gatsby Online, the début production in Seanchai Library’s EXPLORE the Stories Behind the Art series, will open its doors on January 14th, 2015. It will offer visitors the opportunity to visit key locations from the novel and play, and in doing so learn more about the era in which the story is set, explore Fitzgerald’s life and writings and discover more about the theatre in which the play is being performed.

On offer within Seanchai Library’s virtual environments will be a reproduction of the fictional West Egg, where the story’s narrator, Nick Carraway rents a small holiday guest house, only to find himself living next door to the enigmatic Jay Gatsby, giver of lavish summer parties. Both Carraway’s little holiday house and Gatsby’s mansion will be open to explore.

Also presented with the Explore Gatsby facilities will be a portion of East Egg, where Daisy Buschanan, the subject of Gatsby’s desires, lives in opulence with her husband Tom. Here, behind the Buchanan mansion’s façade, will reside a reproduction of the Tacoma Little Theatre itself, offering the opportunity for people to discover more about the theatre itself, which is among the oldest community theatres in the United States, and the oldest on the U.S. west coast, with a rich heritage going back to 1918.

And, of course, there will be the opportunity to visit the so-called “Valley of Ashes”, the industrial dumping ground so pivotal to the unfolding story, which lies between the fictional East and West Egg and the beating heart of New York City.

These various locations will serve as venues for a range of live events which both support TLT’s production of The Great Gatsby and which also encourage visitors to further immerse themselves in literature, the stage and more; there will be readings and performances from the novel, interactive elements, within the various settings will provide information on a broad range of subjects, including information on the 1920s and the social issues people living then faced, the characters from the novel, etc.

Explore Gatsby will essentially be an educational study guide brought to three dimensional life. Through a special portal currently being developed by Seanchai Library, visitors will be able to learn how to download and use a viewer and operate an avatar, and then connect to Explore Gatsby in Kitely.

Tacoma Little Theatre will feature in Explore Gatsby, allowing people to discover more about this historic community theatre

Of special note with the project is the fact TLT present daytime performances of the plays they stage for local schools to attend. Thus, through their Explore Gatsby partnership with Seanchai Library TLT is presented with a dramatic – no pun intended – new way to engage with teachers, educators and school children in an immersive manner which links the performance of the play directly with classroom learning opportunities. The same also goes for TLT’s patrons, who can take a performance of The Great Gatsby home with them and them delve into Gatsby’s world through the Seanchai Library’s virtual recreations and events.

As noted above, Explore Gatsby will be opening its doors on Wednesday, January 14th, 2015, with in-world events and activities commencing on Friday, January 16th. Everyone involved in virtual worlds is extended a warm invitation to pop along and join in with planned activities as they take place – a programme calendar will be available nearer the time, and I’ll also be presenting it through these pages.

I’ve been privileged to be associated with Seanchai Library for a while now, and as a part of this association, I will be covering Explore Gatsby and the EXPLORE the Stories Behind the Art series as it develops. I’ll be kicking-off things in due course with a behind-the-scenes look at preparations for the début production.
